Abstract: PURPOSE:To set optimum threshold value so that excellent binarized picture can be obtained independently of lower or higher background level, by using the ratio of circumference length to density, in a character picture. CONSTITUTION:Density information from a cyclic register 6 storing density information of picture is binarized at a binarizing section 3, and the result is applied to the circumference length ratio (length of circumference/number of black video elements) operation section 2, where binarized video elements are read in through a buffer memory 7 to calculate the length of circumference and the circumference length ratio. When the ratio for a certain density is finished to obtain, the ratio is applied to a threshold value operation section 4 and the binarizing section 3, and the same is made with different density. The section 4 receives the threshold value and density this time together with the ratio from the section 2, to calculate an optimum threshold value from the relation between the circumference length ratio and the density.

Title: Rewritable optical recording and reproducing device
Inventor: ISHIDA TAKASHI
IPC: G11B7/125
Filed: 1984-05-21
Abstract: PURPOSE:To ensure the complete erasion over the entire circumference of a recording medium by changing a spot form and the light intensity in response to the position of an erasion light spot in the diameter direction of a disk-shaped recording medium and keeping a constant heating/cooling state of the recording medium in an erasion mode. CONSTITUTION:A cylindrical lens 16 can move in both directions A and B and are positioned so that the direction of a light beam corresponding to the circumference direction on a disk 1 is diffracted. An oval spot is produced when the lens 16 is shifted in either direction A or B, and the diameter of the spot is changed in the circumference direction of the disk. The lens 16 is shifted properly toward A and B at the outer and inner circumferential areas of the disk respectively. The spot diameter is increased toward the outer circumference side. Thus the transmission time of a record bit within an erasion light spot, i.e., the irradiation time of the erasion light to the record bit can be kept equal between the inner and outer circumferential areas of the disk. This secures a constant heating/cooling state at the entire circumference of the disk to a recording material and ensures the complete erasion.

Abstract: PURPOSE:To reduce the load of an input/output bus and an input/output controller by using a cyclic sequence number and an answer request flag in order to omit a process where the occurrence of an error is reported to the input/ output controller when no writing error is produced to a main memory means. CONSTITUTION:When an access request is given to a main memory 2 from an input/output controller 4, a bus control part 14 generates an answer request flag to show whether a cyclic sequence number (S) and the return of an answer should be requested or not and stores this flag into a request buffer memory part 12. When the output is possible for the information stored in the part 12, the part 14 secures an input/output bus 6 to send the address of the controller 4 to the bus 6 as the address information as well as the error information and an S signal as the data information respectively. The controller 4 detects that its own address is sent to the bus 6 and fetches the data on the bus 6 to know a specific access request of the number S is over normally or abnormally. Then a process where an access request is reported to the controller 4 when said request is over normally.
